1. In a nursing home, a program is launched in 2005 to assess the extent to which its residents are affected by diabetes. Each resident has a blood test and 48 of the 625 residents have diabetes in 2005.  Residents who did not already have diabetes were again tested in 2010 and 57 residents had diabetes.

What is the prevalence of diabetes in 2005?

Prevalence 2005 = ________

What is the cumulative incidence of diabetes over 5 years?

Cumulative Incidence 5 Years = ________

What is the prevalence of diabetes in 2010 (assume that none of the residents in 2005 have died or left the nursing home)?

Prevalence 2010 = ________

Step 1

given 48 out of 625 residents have diabetis in 2005.

The number of residents with diabetis in 2010, who did not have diabetis earlier = 57.

Prevalance is  the number of cases of a disease that are present in a particular population at a given time and is calculated by below mentioned formula. By substituting values we get prevalance of diabetis in 2005 =  0.0768.

Step 2

Cumulative incidence  measures the number of new cases per person in the population over a defined period of time.

The total number of residents with out diabetis and who are at risk &nbs...
